This invention has reference to im rovements in the manufacture of boxesof su stantially flexible material and it relates in particular to meansof applying pasting pieces of other purposes and for applying printed orstamped matter to the box sections or for directly printing and stampingthe same or for submitting them to the treatment by means of dies andthe like. The box sections in these i turn to its initial position whichresults inv operations are preferably treated in the WellknoWn manner bycircularly arranged printing and stamping instrumentalities mounted on aturntable, the said instrumentalities, dies, pressing and printingmeans, stamps and the like being operated and controlled in accordancewith this invention from a cam roller which is so arranged andconstructed that it will participate in the-partial movements of theturntable or the like carrying the printing or pressing means, Whileafter each individual partial rotation the cam roller will rethelowering of the printing lor pressing means, plunger or the like at thefeeding stav tion of the box sections and the simultaneous raising ofthe plunger or the like on the stationsoperating as ejecting means,While the pressing and printing instrumentalities which happen to be inthe printing or stamping position will not be operated. It is anotherobject of this invention to provide a safety appliance inconnection withthe other instrumentalities, by means of which the admission of a pieceor slip of coating paper which acquires adhesiveness by heat to thecharging station of the box sections is prevented, in case of deficientfeeding of a box section from any reason, so as to obvia-te thepossibility of a piece of coating paper or the like being forced into anempty matrix and adhering to the pressing die or the like.

The invention will be further described by reference to the accompanyingdrawing showing by way of exemplification a preferred embodiment of theprinciples thereof,

Upon the base plate 1 and by means of posts 2 a'rotary carrier ismounted comprising a table plate 3 which carries the supports 4 withrollers 5. Upon these rollers the outer marginal portion of a turntable6 is adapted to rest which is secured to a vertical shaft 7 which issupported on the base plate 1. Above the turntable 6 a cross-shapedskeleton bearing member 9 is arranged the apertures 10 of which lservefor the vertical guiding of the rods 11 of the pressing dies or plungers12 the reciprocation of which in the ver"- tical direction is elfectedby a cam cylinder 13 in the vcam groove 62 of which the free ends of therods 11 are suspended by means of rollers 14. The cam 13 is retained inposition on its top portion by the guide rollers 70. Below the pressingvlungers or dies 12 matrices 15 are arranged? each matrix having asupporting stem 15a slidably engaging the bore of a bracket member 15band yieldingly supported therein by a backing spring 15e. vThe heatingof .the matrices may be effected by gas burners or thelike 16. Thelturntable 6 is operated bypmeans ofa train of gearing 66 and by thetransmission gear'- ing 17 from a Geneva movement 18 which is driven bya roller 19 (Fig. 2) secured to 21 on the shaft 22 which transmits itsmovement by means of bevel gear wheels or initre wheels 58 to a shaft 59(Fig. 4). On shaft 22 is a gear 22 receiving inotioii from a pinion 22bon a drive shaft 22c carrying pulleys 2,2d oi: other means for rcceiyingmotion from any suitable source of power. A dog or lock bar 24 which isoperated by a'cani' surface of apdouble. cam disc 23V,mounted'v upon theshaft 59 (Figs. 4 and 5) serves for the arresting of the shaft 7 and of.the turn table 6, after the feeding of the Geneva wheel 18. On the shaft22 a cani disc 25 is disposed which, by means of a lever 26. and thevertically disposed transmission shaft 2i carryingsaidlevelr operatesand controls a Ptoothed'segnienth28 (Figure 2) which trans- I nitsv itsoscillatingmovement to a curved rack orgear wheel 2901i the cani 13 and'in consequence' thereof this Cain is compelled vto perform anoscillatory movement likewise.

tha't is to say, first the movementI in the saine direction as the.`turn-table 6, and upon the reversal of the Ymovement'of thesegni'entfi'n 'the direction opposite to that of the turntable. .Aconveyor 30 transfers the box sections31 to a platform 32 (Figures 1 and2) froin'wliich they are carried across the vmatrices y15 substantiallyat right angle to the direction of movement of the apron' or `.conveyor30 and during this movement they are supported ybynarrow and spring sup-37, a bar 38, anda spring 38. and to -which downward movement isimparted through a cam roller 39 from a cani disc 40 on the shaft 5S).The suction device delivers the paper wrapper 31 between thetongs orgrippers 41, 71. Tongs 41 are mounted on non-.circular rods 72 which arerotatably and slidably itted in bear-ing eyes 73, 74. Onathe rods 72,between the veyes 74, are mounted crank arms 75 connectedby rods 76 withspringpresscd bell-crank levers 77 carrying rollers 78 whichrespectively bear against a cam surface of the double ani disk 23.heretofore referred to, and against the cani surface of another caindisk 23', ou ,the rotationL which thctongs 41 are raised and lowered(opened and closed with respect to tongs 71) at proper intervals. Thetongs 7l bars 42 which arc..,i no\ jable to and fro by Atongs-41areythen loweredvso as to claiiip the wrapper between them and the tongs71 and the-ntheclosed tongs, carrying with them the wrapper, are movedby parts42, 42 toward-the -niatrix 15 which is in receiving` positionuntil the wrapper lies Vabove and in exact registry with the matrix. Atthis moment tongs'41'are again lift-ed, thus releasing the wrapper 34which drops vonto the finan-ix.'l Parts 42,'[42 then operate t'oreturnthe tongs to initial position. The box section 31 arriving yby way ofthecoiiveying apron upon'the platform 32 is pushed' below the pressingplunger or die 12-and ab'ovethe anvil or matrix `15 by .i` slide 44`(Fig. 7) and by the action of a spring '4.6l acting uponthe two-armedlever 45. The lmovement vof 4the lever 45 is produced .byniean-sof acani disc 47 upon the shaft 59, uponwhich cam discthe free'end of saidtwo-armed lever 45 is adapted to bear. To theslide or push arm 44 asafety device "is connected which consists of a locking pin 48 (Figures5 and 7) adapted to become engaged behind an adjustable liig 50 of a.feeler 50 keyed to the shaft49 and rotatable therewith so that theslide'willbe locked from movement un'tilftli'e.

pinis released'by the'feeler. Further. this Afee-ler 50 acts on a bar52. .with which it is connected by lever 51, which latter is' heldrigidly on the pivot pin 49 of the feeler. The other end of the bar 52isinounted on the standard pillar 2 in the slot' or bifurcation of ahorizontally bifiircated guide inem"- ber 53, viii tlic top and bottomwalls of which are registering cut-outs 54; and on the bar 52 there isprovided a'corresponding' cut-out. 54. Depending upon the position ofthe ffeeler 50the bar 52 is: either in the, yposition according to Figs.7 and 7a or according to Figs.,8 and 8a. ln thefirst-named position thecut-out 54 is at one side o1 or out of registry with cutout 5-'1-.whilein thi` other position the cutouts 54 register.'v ln Fig.

'7a one finger 38 of hai' 38, VHwhich latter 'moves the sucker 35. socontacts with thc -bar 52that the linger is held in itslo-werniostposition. But if tl'ie bar (Fig. 8) is moved to bring cut-outs 54, 54into registry. then finger 38 Acan pass through cut-out -54 of bar 52iipwardly. lf. them-feelin' 5t) is moved through a box 3l in upwarddirection (Fig. 8) andthe cani disk 40 releases the rod 38, then thespring 38 will pull the rod 38 so far upwardly. that the linger38"engages in the cut-out 54 and the sucker 35 Yis moved over toward thepile 34. If a box fails to arrive, `then the -feelcry likewise willremain inthe p'ositioiiFig.l 7, the cut-out '54 jb'eingout of registrywith thecut-outs` 51 of guide If now the rod 38is'released` from'"thecani disk`40, then'it is prevented from ascending because linger38"contacts with Ofll'fst e .s from pile 134. Another'slide o`1 pusharm`55 `(Figure 2) parallel 'to the' slide Hand operbar'. 52, the sucker35 rei'nains in its position and no cover paperis withdrawn ated by asyst-em of levers 67: serves for the 'ejectionl offthe finished boxportions', The

saidarni carries fingers'or the vlike' 56 (Figi'iref2) on the 'arms 68,which `inthe operative position `aredisposed above lthe frame o f'thedie or matrice 15 and push the box portion offjthe same upon the raisingof the pressing die o rpliinger'l. Anangle .piece 5T (Figu'i'e'2)securedvto'oi'ie of said arms 67, leads the box to be vdelivered onto.`

`an inclined chute orpiece of sliee'tfn'ietal 69.

' The operation of the vdevice described is substantially'as follows:The prepared box sections 31 are conducted by theconveying apron-or thelike 80 to theplatform 32 where theywill press against the feeler thelock v ing'lug 50 of which will become disengagedl and Will releasetheslidej'or push lbar 44.

` Bars 61 rockingly disposed onthe shaft 60 (Figures land 3.) arebearing at the saine time with their free ends upon the box `sections,so thatowing to sufficient' friction with the conveying apron'beingproduced thereby the. reliable feeding forward of the boxparts l and therelease of the f eeler arrangement f will only take place, when: the boxsection 'l has assunieditsproper position with relation to the slide 44.This slide will then push lthel fbox section sideways at substantiallyright `angle tothe lp re'v'ious direction of movement ontothedieormatrice 15 located at the j pressing station I wherethe boxsectionrests upon'the spring acting guide barsi33. At the saine time lawrapping paper is pulled off the-pile by the suction member 3 5,inasmuch as by` the release of the slide4f1 the locking of the bar 38has been discontinued, the said piece of lwrapper beingr placed acrossthel matrice 15 by thetongs 41. The plunger or pressing die 12 islowered by means of the cani race of the cam 13 and forces the b oxsection 31 upon the wrapping paper 34 Figure 10), while thesupporting'bars 33 spiing actingly yield in the downward direction. Bythe use of the heated matrice 15 the pasting of the wrapping orenveloping paper 1s effected in the usual manner, the paste upon saidwrapping paper becoming sticky by heat, and upon continuing the downwardmovement of the plunger 12 the box parts are pressed together and united(Fig. 11). Under the action of this compressing pressure the box part ismoved through the other treating stations II, III, IV. On the laststation the compressing pressure is released,

invention, as expr the plunger or pressing die is raised,'and thefingers 56 of the -pusher or slide 55 push the finished box partoi'fthepressing die 12,'and

the pusher eiect-s it into the chute 69.

The raised' portion of the cam race 62 (Figur'e 2) moves up and downbetween the stations I and movement o IVin viewof the reciprocating thecompression and the ejection at these stations is produced. ThecamlSparticipates with the same' angular velocity in the partialrotations of the tiirnt'able 6, While 'after each partial rotation it isrotated back again into its initiall position bythe' segment28. In

this last stage of movementth'e `plunger or pressing dieA 12 is loweredat the charging stationI, and atl the ejecting station the pluiigcrissimultaneoi'isly" raised, kwhereupon by means of thethen following'partial rotation of the tu'rIiLtable 6' together ywith-the roi'tation'of'fthe cam 13' 'this raised plunger is transferred to the stationI. Atthe stations II 'and I II the pressing'dies or plungers 12 remainint-heir lowered position. i -Instead of four stations a greater' numberthereofniay obviously' be employed, so that the duration ofthep'ressing'operation is extended.
